Objective 23 & 24: Major vessels entering and leaving the heart & Structures of the heart

I found a great website that got me in tune about the structure of the heart and the major vessels entering and leaving the heart.  The website is http://www.skillstat.com/heartscape/basicFacts.htm#BasicFacts
There are just too many structures of the heart for me to detail so I think this website sums it up quite nicely because it really helped me learn it.

Also the above diagram shows the major vessels entering and leaving the heart.  The left side pumps oxygenated blood and the right deoxygenated blood.  This diagram was found here. http://www.ukdivers.net/physiology/heart.htm
